Burks bklugb vortex flowmeter, plug-in vortex flowmeter

Vortex flowmeter is composed of vortex generator, detection probe and relevant electronic circuit designed in the flow field. When the fluid flows through the triangular cylinder vortex generator, two alternate rows of vortices are formed on both sides of it. This kind of vortices is called Carmen vortex street Strouhal in Carmen vortex street On the basis of the theory, it is put forward that the frequency of Carmen vortex street is directly proportional to the velocity of the fluid, and the relationship between frequency and velocity is given: F = stxv / d

Where: F -- frequency of vortex street (Hz) V -- average velocity on both sides of vortex body (M / s)

St -- Strouhal coefficient (constant) d -- inner diameter

These alternant vortices form a series of alternant negative pressure. When the pressure acts on the detection probe, a series of alternant electrical signals are generated. After the preamplifier is converted, shaped and amplified, the pulse frequency signal (or standard signal) which is proportional to the vortex synchronization is output.
